So, for now there is no software on the market for manipulating
S7000 RAW files. Perhaps in future.

There are many freeware raw converters (s7raw, s7000raw, just try a search) that, while not as complete as say Photoshop CS Raw interface, have more features than Fuji RAW converter LE. For example: white balance setting, gamma setting, 48bpp output,...

But I agree that Fuji should provide us, at a basic price, a more capable raw converter.
